First of all, I haven't played Valorant or any Riot-related games for 3-4 months because of exams.
A couple of months ago someone got into my pc and stole the credentials of a lot of personal accounts including the riot one, but since i haven't played at all i didn't notice they stole my riot account. I have receipts of in-game purchases and my personal phone number connected to the account because of premiere. Is it possible to get it back? I tried to use the official support, but the chat bot is not helping at all
